Dear Colleagues, Thank you for comments and remarks. Many thanks to Mark for his interesting post. Really, the correspondence between energy and information is fundamental and needs to be clearly explained. I want to present my point of view because it is different from other ones. It is
Dear Krassimir et al., I like your view very much with one exception. I think it confounds information with meaning, which I think can lead to problems. For example, I could give two people the same message written on your identical pieces of paper. It is written in English, but only one of
